5.7 x 28MM

5.7×28mm covers ammunition developed for FN’s high-velocity small-caliber cartridge, originally designed for personal defense weapons and later adopted in both military and civilian platforms. Introduced in the late twentieth century, the cartridge is characterized by its bottlenecked case, lightweight projectiles, and wide range of specialized loadings.

This category includes military and commercial ball ammunition, hollow point and sporting loads, armor-piercing and tracer variants, blanks, dummies, experimental wildcats, subsonic pistol loads, and manufacturer-specific designs. Variations in projectile construction, core materials, tip color coding, case finish, and packaging reflect the cartridge’s specialized roles and ongoing development. The material here is especially useful for collectors interested in modern PDW ammunition, late–Cold War small-arms innovation, and the technical divergence between traditional pistol cartridges and high-velocity compact rifle systems.
